Hi Paul,
The aluminium back end of all of the trikes is always protected, in the case of the VTX by a tough powder coat paint finish and in the case of the Sprint, Adventure and other trikes by an anodised finish. There is also a plastic shim in there which stops direct contact between the two materials even in the case that the finish is damaged. We have been producing trikes with steel cruciforms for about 20 years and trikes with steel cruciform and aluminium back ends and booms for over 6 years and we do not see the issues that the forum members are worrying about. The benefits of the different properties of the materials outweigh any potential issues with corrosion which might occur because of the dissimilar metals.
If you wanted to pull out the back end and boom and treat the inside of the main frame with a product like framesaver occasionally it certainly wouldn’t hurt but I wouldn’t say it is vital unless you regularly ride in salty or other corrosive conditions.
Thanks,
Patrick

Thanks, Paul. Double protection (Powder coat or anodizing and plastic shim), so galvanic corrosion is a non-issue, unless the rear section is removed from the cruciform frequently, causing finish and shim damage. Then, application of Framesaver, particularly in a wet area where road salt is present, would be a good idea.
